YINHAI ROCK BITS FACTORY PROFILE

 

YINHAI Tricone Bits/ Roller Cone Bits Details:
Tungsten Carbide Inserts Bits /TCI & Steel tooth tricone bits/MT, from 3 7/8 to 28 inch (3 7/8" ~ 28").
--- Our advantage & features:
   1. Bearing polishing process improves the service life

   2. Hardfacing and Tungsten Carbide Inserts for Leg and shirttail protection

   3. Heel Inserts and Build up welding on the Steel milled teeth

--- Since the end of 2021, our factory has added a new process for better bearing performance--bearing polishing,
    We polish the bearing after finished turning, After polishing, it is very smooth like mirror, very very smooth and shining.
    Extend the service life of our drill bits, allowing customers to get a better quality product for the same value.
--- YINHAI TRICONE BITS, ENGINEERED TO DRILL:
    IADC 117/217/327, IADC 417/437/517/537/637 (435/535/635), Steel Milled Tooth and Chisel/ Scoop/ Conical/ Sphrical Inserts Teeth
    Suitable for Water, Oil, Gas, Geothermal well drilling, Mining and HDD drilling
